CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 363,800, dated May 31, 1887.

Application filed April 13, 1887. Serial 1\ o. 234,685. (No model.) 4

ings, and'hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal section of my improved coupling. Fig. 2 is a cross-section, and Fig. 3 is a detailed view.

Referring to the drawings by letter, A designates the draw-head, which may be secured to the bottom of the car in any desired man-' ner., The top of the draw-head is open, as shown, and across the top, at the front end thereof, I secure the bar a, which is provided with the central vertical opening, B. A similar opening, I), is provided in the bottom of the draw-head in alignment with the opening B, so that, when so desired, the draw-head may be used with the ordinary pin and-linkcoupling. A spring actuated plunger, 0, is provided in the rear end of the draw-head and acts upon the link in the manner hereinafter specified.

A gravity-pawl, D, is pivoted in the drawhead near the front end of the same and engages the link in the operation of the device. Alockingblock, E, is pivoted eccentrically on the front side of a shoulder, e, and when it is in its normal position prevents the withdrawal of the gravity-pawl. As will be seen from the drawings, this locking-block is pivoted near one corner, and the said corner is beveled or cut away, as shown. By this construction,

when the locking-block is in its normal position, an attempt to lift the pawl will cause it to bind against the lower edge of the locking block, and its removal will thereby be prerod or chain running to the top of the car, in order to uncouple the cars without the neces:

sity of the attendants going between the same.

G is the link, consisting. of a metal bar having pointed enlargements g at its ends and provided on the inner sides of said enlargements with theshoulders H H, as shown.

In operation, the link enters the draw-head and the gravity-pawl automatically falls into engagement with the shoulders of the link, and they are held in engagement by the plunger in the draw-head acting on the link and tending to press it out of the draw-head.

I Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination, with the draw-head, of the link, the gravitypawl pivoted in the drawhead and engaging the link, and the lockingblock mounted in the draw-head in rear of the gravity-pawl and in the path of the same, substantial] y as set forth.

. 2. The combination, with thedraw-head and the link, of the gravity-pawl pivoted in the drawhead and engaging the link, and the locking-block pivoted ecccntrically in rear of the gravity-pawl and having its front face bev-..

eled from its pivotal point to the nearest edge, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed m y signature in presence of two witnesses.

LOUIS CHAMPAGNE.
